Introduction Kenya ranks fifteenth among the twenty two high tuberculosis burden countries that contribute to 80% of the global tuberculosis burden. It is imperative to scale up tuberculosis eradication interventions in order to reduce morbidity and mortality and promote health for all. To achieve this, it is critical that drugs are consistently available to treat patients, prevent spread of the disease and minimize drug resistance. Health facilities within Nakuru County have been experiencing severe shortages of various anti-tuberculosis medicines. This is likely to be due to weaknesses in the tuberculosis medicines management practices at the facility level. The objectives of the study were to establish the effect of inventory analysis method practiced and the information tools in use on the availability of essential anti-tuberculosis medicines at health facilities in Nakuru County.MethodsThe study was conducted in January 2015 at 31 health facilities in Nakuru Central, Gilgil and Naivasha Sub-counties. These were purposefully selected as they had 90.4% of the total tuberculosis cases in 2012. Ethics approval was obtained from the Kenya Methodist University Research and Ethics Department. Permission to conduct the study was obtained from the Nakuru County Health Department. This was a cross sectional study. Stratified sampling was used to randomly select the 31 health facilities from sub-county and facility level strata. Each facility had one respondent hence the study involved 31 health care staff involved in tuberculosis medicines inventory management. Data was collected through self-administered structured questionnaires. There was a 100% response rate.ResultsMajority of the health facilities that had good availability of tuberculosis medicines practiced the maximum-minimum method of inventory analysis. Facilities practicing ABC system were 15 times more likely to experience unavailability of TB commodities as compared to those practicing Maximum –Minimum (Odds ratio = 15.0(1.5-149.7), p =0 .021). The information tools were available in all facilities; however, the proportion of use was always lower than proportion of availability. The association between availability of the data tools and availability of tuberculosis medicines was not significant (Daily Activity Register (DAR) odds ratio = 0.9 (0.2-4.3), p-value = 0.981); Facility Consumption Data Requisition & Report Form (F-CDRR) odds ratio = 0.7(0.1-3.8),p-value = 0.679; Requisition & Issue vouchers (SLLs) odds ratio = 1.8(0.2-15.0),p-value = 0.576)).Majority 26 (83.9%) of the respondents had adequate storage capacity. They however cited storage challenges which varied insignificantly with availability of tuberculosis medicines (P =.056).
